CURTAIN-ADJUSTER.

Application filed October 15, 1919.

To all whom it may concern: 7

Be it known that I, GEORGE W. HUM- PHREYS, a citizen of the UnitedStates of America, and resident of Kansas City, in the county of Jacksonand State of Missouri, have invented certain new and useful Improvementsin Curtain-Adjusters, of Which the following is a specification.

This invention relates to brackets for shade rollers and particularly tomeans for supporting a shade roller and to novel means for rotating theroller for the purpose of unwinding or winding the shade with relationto the said roller.

An object of this invention is to provide a novel casing with arotatable member mounted therein and having a projectmg spindle adaptedto engage a fixture of the shade roller, whereby the movement of therotating member may be communicated to the said roller.

A still further object of this invention is to provide flexible memberscooperating with a drum, the said drum being mounted in a casin so thatthe drum may be rotated in di flerent directions by a pull on theflexible members.

A. still further object of this invention is to provide novel means forfrictionally retaining the parts against movement when a predeterminedadjustment has been attained.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed. In describingthe invention in detail, reference will be had to the accompanyingdrawings forming part of this specification wherein like charactersdenote corresponding parts in the several views, and in which Figure 1illustrates a perspective view of a fixture embodying the invention;

Fig. 2 illustrates a vertical sectional view thereof; and

Fig. 3 illustrates a rear view showing the bracket attached to thecasing.

In these drawings 5 denotes a casing having a bracket 6 with aperturedears 7 and 8 through which the fastenings may be applied to hold thecasing in position.

A plate 9 has an aperture 10 and the said plate is located in the casingand constitutes a bearing for the spindle or shaft 11 and the saidmember 11 has a projecting end 12 Specification of Letters Patent.

Patented Dec. 16, 1919;

Serial No. 330,776.

The spindle or shaft 11 to be hereinafter termed a spindle, has drums 13and 14: mounted on it within the casing and the said drums are separatedby a plate 15 which projects beyond the drum to form a flange to confinethe flexible members 16 and 17, theformer of which is wound on the drum13 and the latter of which is wound on the drum 14. The flexible membersproject through the apertures 18 and 19 respectively in the casing andthe member 16 is wound on the drum 13 in an opposite direction to thatof the winding of the flexible member 17 so that a pull exerted 011 oneof the flexible members will rotate the spindle 11 in one direction,whereas a pull on the other flexible member will rotate the spindle inthe opposite direction, and of course, one flexible member will berewound while the flexible member under tension is being unwound.

A bearing plate 20 is held in the casing by the cap or closure 21 whichlatter has a flange 22 which engages the outer surface of the casing andfrictionally retains the cap or cover in place, thereby holding thebearing plate so that the spindle will be rotatably mounted in thecasing. I

The flange 22 has a recess or notch 23 which is adapted to aline withthe aperture 19 to permit the free movement of the flexible member 17,but if it is desired to set the device so that it cannot be readilymoved or so that it cannot be accidentally moved, the cap or cover ispartially rotated so that an edge of the notch binds against theflexible member with sufficient friction to retard the movement, therebyholding the drum against rotation.

As the fixture can be made by the stamping process as to the bracket,casing, cap and bearing plates, the said fixture may be inexpensivelyproduced-as it will of course prove durable on account of the fact thatthere are no parts which are subjected to undue wear.

I claim- 1. In a fixture for curtain rollers, a casing, a bracketattached thereto, a cover for the casing having a flange, the saidcasing having apertures, a spindle, means for rotatably mounting thespindle in the casing, the said spindle projecting through the cover andhaving a projecting end angular in cross section for connection to acurtain roller, drums mounted to rotate With the spindle, a plate on thespindle holding the drums in spaced relation to each other and havingitsperiphery extending beyond the peripheries of the drum, flexible membersWound oppositely on the drums and held apart by the said plate, the saidflexible members projecting through the apertures of the casing.

2. In a fixture for curtain rollers, a casing, a bracket attachedthereto, said casing having apertures in its side, a cover for thecasing having a flange With a notch therein adapted to aline with one ofthe apertures of the casing, a spindle, means for rotatably mounting thespindle in the casing, the said spindle projecting through the cover andhaving a projecting end angular in cross section for connection to acurtain roller, drums mounted to rotate with the spindle, a plate on thespindle holding the drums in spaced relation to each other and havingits periphery extending beyond the peripheries oi the drums, flexiblemembers Wound oppositely on the drums and held apart by the said plate,the said flexible members projecting through the apertures of thecasing.

GEORGE W. HUMPHREYS.
